Flying has always been this wonderful metaphor to me. In order to fly you have to trust what you can't see.Up on the mountain ridges, where very few people have been, I have thought back to what every flyer knows.That there is this special world in which we dwell, that is not marked by boundaries. It is not a map.We are not hedged about with walls and desks.So often in an office,the very worst thing that can happen is you could drop your pencil.Out there's a reminder that are a lot worst things, and a lot greater rewards.
